The "Heartbleed" vulnerability in OpenSSL (CVE-2014-0160) is a bounds checking
error in the heartbeat implementation that could return up to 64K of private
data to the client. This can lead to server certificate private keys, session
cookies, clear text passwords, or other sensitive data being leaked from the
server to the client. This vulnerability exists in OpenSSL versions 1.0.1 through 1.0.1f and 1.0.2 beta.

It is important for server administrators to update OpenSSL as soon as possible
and take steps to secure any private data which may have been leaked. This may
include updating server certificates and revoking certificates that may have
been compromised.

Users should ensure that web sites they use have been secured and should update
passwords or other authentication information.
